Can anyone explain if the specimen was found through rigorous research or just sheer luck? Because it is starting to seem like it's the latter.

No idea if accurate but there was this which is interesting: https://news.ycombinator.com/item?id=36996337

> “ Specifically they were one of the last believers of long-forgotten Russian theory of superconductivity, pioneered by Nikolay Bogolyubov. The accepted theory is entirely based on Cooper pairs, but this theory suggests that a sufficient constraint on electrons may allow superconductivity without actual Cooper pairs. This requires carefully positioned point defects in the crystalline structure, which contemporary scientists consider unlikely and such mode of SC was never formally categorized unlike type-I and type-II SC. Professor Tong-seek Chair (최동식) represented a regret about this status quo (in 90s, but still applies today) that this theory was largely forgotten without the proper assessment after the fall of USSR. It was also a very interesting twist that Iris Alexandria, "that Russian catgirl chemist", had an advisor who was a physicist-cum-biochemist studied this theory and as a result were so familiar with the theory that they were able to tell if replications follow the theoretical prediction.”

So it might be an old hypothesis brought back?

Earlier quoted context omitted.

Assuming everything in the video is real, the only remaining question is: what is the actual temperature of that sample? If all of this checks out, then it's a new era.

Such tiny samples warm up to room temperature very quickly, on the order of a few seconds. In my experience, it's not possible to make such small pieces of YBCO superconductor levitate, they warm up too fast.

No frost on the sample either. The only way I can think of to fake this in camera is to make the "sample" out of a strong magnet, and make the "magnet" a hollow shell concealing a chilled piece of YBCO!

This is basically proof of room temperature superconductivity correct? (Of course assuming it isn't a hoax)

This is an hoax and it's sad to see people like Sabine Hossenfelder falling for it so easily: - video recorder in a kitchen or living room - created by some random tiktok account - no credentials, no description - tagged "mysterious" It's hard to understand how anyone would believe this, specially after so many other fakes

Hoax is quite a strong word where there's been quite a few replication attempts with various degrees of success. Like others have said, we're not sure what this is, but it almost certainly isn't a hoax.

As for this video, well, it's like all the other ones that came before it, we'll know more once we have more data/videos/replication attempts.

Some of the other videos were at least from some more or less reputable sources. This one appears to be anonymous, or am I wrong?

[Citation needed] - What linked patent? It seems incredibly rude to me to dismiss decades of dedicated research this way. This is a human achievement, it's not right to try to take that away from the people who put so much work into it.
